The colourful bow was thought to be positioned in the Towers/Romney Park area.
In Christianity, the rainbow is a sign of grace and a promise made by God to never flood the entire earth again.
“This is the sign of the covenant which I make between Me and you, and every living creature that is with you, for perpetual generations: I set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth. It shall be, when I bring a cloud over the earth, that the rainbow shall be seen in the cloud; and I will remember My covenant which is between Me and you and every living creature of all flesh; the waters shall never again become a flood to destroy all flesh”- Genesis 9: 12-15 (NKJV).
Bible scholar John Gill states concerning the rainbow, “as it has in it a variety of beautiful colours, it may represent Christ, who is full of grace and truth, and fairer than the children of men; and may be considered as a symbol of peace and reconciliation by him, whom God looks unto, and remembers the covenant of his grace he has made with him and his chosen ones in him; and who is the rainbow round about the throne of God, and the way of access unto it.”
The colours of the rainbow are also used on a flag for the gay and lesbian movement.
